For fellow Crunchers who also love Cartier FYI
The Cartier AD where I purchased my ADLC Santos emailed me a link from Cartier to extend the warranty on the timepiece at no additional cost. Once I registered the serial number, my international limited warranty was extended 6 more years to 2029 (a total of eight years from the original purchase).
The base limited warranty covers 2 years from initial purchase but now that I look at my warranty card it does provide a QR code to up to 8 years of international limited warranty which I must have neglected to do when I initially registered my watch with Cartier. So, you too might want to check to see if you've registered with Cartier Care to ensure you're getting the extended warranty as well.
